Teach ASTWalker to walk some more implicit expressions and declarations generated by the type-checker. Unfortunately, it's not possible to directly check this because the verifier is itself based on ASTWalker. But I'm going to add an assertion to SILGen in a follow-up that assumes that TypeCheckError has visited every ApplyExpr, and since SILGen already walks most of the AST with its own custom walker, that will check this well enough.
